Senior Fullstack Engineer (Backend-Leaning | TypeScript/NodeJS/AWS) 
London (Paddington) | 3 days onsite
£70k–£85k

We’re working with a fast-growing, VC-backed data platform helping global brands understand and monetise user behavior in next-gen digital environments.


The role

  • Backend-leaning fullstack (80/20 split)
  • Build and improve core data systems + APIs
  • Work heavily with data pipelines (S3, transformations, high-volume data)
  • Own features end-to-end (API/DB/internal tools)
  • Help level up a growing engineering team

Tech
TypeScript, Node.js, React
AWS (incl. S3), Kubernetes
MySQL, MongoDB, Elasticsearch


What they want

  • Strong TypeScript engineer with real backend depth
  • Startup / small team experience (must be comfortable with pace + tradeoffs)
  • Solid database design + API experience
  • Proactive — someone who improves systems, not just works within them
  • Comfortable mentoring and reviewing others’ code

Why join

  • High ownership — real influence on architecture + direction
  • Early-stage engineering team, big scope to shape things
  • Interesting data problems (not basic CRUD)
  • Fast-moving environment, no big-company bureaucracy
  • Equity upside

Process
3 stages, fast turnaround (all can be done in one day, in person)
